Well I had put holidays because I like and enjoy holidays. They have value to me. However I respect and understand why holidays are not celebrated by Jehovah's Witnesses. In many ways I think it adds an extra level of legitimacy to the faith. Especially considering to roots of many of these holidays.
I look at the holiday issue in 3 different ways.
1. I ask if Jesus celebrated such things, and if not, then i dont view it as important to make a custom of it so it now needs further consideration and a conscience decision which leads to me my next two considerations.
2. I ask who established the holiday and for what reason. The roots of some holidays are of religious origins, other origins are simply cultural. I need to determine if I want to be involved in such things and if it will add anything meaningful to my life or worship of my God.
3. I also need to consider the principle laid out by Jesus that we need to keep separate from the world. If I choose to make a custom of the worlds celebrations, then just how separate from the world am I keeping? This is a serious consideration for me because how i apply this principle is in my hands... i want to make sure im keeping separate.
These issues are not a JW thing but issues I would have across the board with religion and its adherents. Social conservatism, bible literalism, and the rejection of scientific advances particular the evolution vs creationism debate. Of course this is an generalization and a huge range can be shown to exist with in the faith.
really these all boil down to 'balance'
Conservatism is about keeping on a middle road...not going to extremes. Bible literalism means the bible is truly from God, it is written for our benefit, its stories are based on truth and fact. Believing that the bible is a guidebook for life adds weight to it, it is not based in myth but on real events that happen to include Gods intervention which adds a supernatural element to it. But for anyone who believes in God, supernatural events are not impossible....the entire universe came into existence by a supernatural event.
And the evolution and Creation debate is not an issue for me because science does not give us any clue as to how life actually got started. It shows how life evolved and developed after it started, while the bible tells us how life got started in the first place. The details between the two are minor and they do not discount each other out.
one thing in particular and i am unsure if this just an extreme side of the faith is the rejection of medical advances. Such as not allowing a dying child to get a blood transfusion. I do not know enough to speculate why this is or how directly it is related to your faith.
Well i would recommend that you
read this brochure which explains in detail why we refuse blood transfusion. From my perspective, there are plenty of medical interventions that I would not want to give to myself or my kids....medical therapies abound in many forms and they are not all good for you. Im sure you wouldnt just accept any old remedy because a doctor said to take it. YOu know, it wasnt so long ago that people were sucking on radioactive throat drops! Would you give one of those to your kids? Maybe 50 years ago you might have because the effects were unknown, but today you would be crazy to take it.
Its no different with blood therapies. There are different forms of it, we accept some but reject others. We reject whole blood transfusions but will accept other transfusions. But we reject blood on the basis of the bible law against using blood or taking blood into your body.
